Application filed November 10, 1927, Serial No. 232,220. .Renewed.February 18, 192s.

One of the objects of my invention is to provide a'safety razor in whichthe guard for the blade edge will serve-as an actuating member forrocking or rotating the blade for sharpening the blade edge.

Another object of arrange the parts of the razor that when the guard andthe blade are out of shaving relation the blade may be folded Within therazor frame for storage and transportation.

In carrying out my, invention I provide a frame, a guardmember-pivotally "carried by the frame,ja blade holderpivotallycarriedby the frame, means to retain the guard member and theblade in shaving relation, and

means cooperative between the guard member and the blade holder, whenthe guard member and the blade holder are out of shaving relation, forcausing rocking or rotation of the blade forsharpening its edge when theguard member is .reciprocated in contact with a sharpening surface. 7Myinvention Comprises novel details of improvement that will be more'fullyh'ereinafterset forth and then "pointed out in the claims. 7 I I vI Reference is to be had tothe accompanying drawings forming a parthereof, wherein Fig. 1 isa side view ofa safety razor embodying myinvention;

Sim1lar numerals of reference indicate corresponding parts in theseveral views.

' The frame 1 of the razor is shown comprising a base 1' and spaceduprights 1 to which base a handle Q is'attached in any desired or wellknown way, such as by riveting.

A pair of spaced arms 3 are pivotally supported at 4 upon and betweenthe uprights I 1", and said arms at one end are shown connected by'acrosspiece 3 serving as afinger the invention is to so Fig. 2 is averticalsection throughFig. 1

In; the example illus trated the guardmember 5 is shown the form of a roller having'a recessed mid-port1on 5between spaced annularprQ ectmg surfaces,5 ,that are adapted to engage afaces 5 of the guard member whenthe parts to sharpening or stropping'surface 6. blade I .7 is adapted to rest upon the projecting-sun betweenthe guard member and the blade edge for.cle arance at the blade forlather during.

shaving. AtS is indicated a bladeholder which may be of any suitableconstruction and is pivotally supported between theuprights 1". Saidblade holder is shownprovlded with pivots 9 atopposite corners,.whichare journaledin holes in the uprights-l The blade holder illustratedcomprises a plate 8 having ears 8 at opposite corners, from which thepivots 9 extend. The blade holder isprovided with gears 10 shown locatedat the pivots 9 for 'rotatingtheblade holder,and the guard member .5 isshown provided with gears llwhich areadapted to meshwith the gears 10when the guard member is folded toward and adjacent to the blade holder,as

indicated in Figs. 2 andlO. Tl1e blade holder plate 8 is provided withlaterally disposed stops or lugs 12 at its .ends near the frontcorners,,which lugs extend edgewise beyond the plate, which plate'isshown recessed at its 7 ends at 8, (Fig. 3), and said lugs are shownoffset from the plane ofplate8. The arms 3 are shown provided withprojections or fingers 13 which are adapted to overlie stops 12 when theparts are in shaving relation to re tain the blade upon the bladeholder, (Fig. 1). Said projections are shown extending inwardlyrespecting the planeof arms 3 to engageithe stops -l2 -whicharespa'cedapart a distance less .thanlthe-distance between said arms topermit] the blade holder to swing between said arms, (Figf3); Asillustrated,
